LLPD d45z

This device is there to protect important networks from direct lightning strikes and back flashovers. Indented to be installed along the protected line, it works perfectly on distribution (sub-transmission) lines with the highest voltage of equipment up to 52 kV.

d69z ensures lightning protection of insulators from flashovers as well as overhead lines from power outages caused by insulation flashover and subsequent fault current flow.

Operational principle

This product operates on the basis of EasyQuench technology.

d45z can easily be adapted to poles/towers of totally different configuration. This is possible due to various installation options.
